Some time later, you look through an arbitrary window and see a slew of tiny white lights rushing by. All the lights appear to move as one group. That is, they all appear to move at one speed and in one direction. You are just looking out the window for the first time, so you do know when, if ever, the lights had begun to behave in this manner. Required:
Draw a neat and clear sketch of what you see through the window. Use arrows of thoughtfully chosen sizes and directions to indicate any motion you observe.
